Problems solved by technology

The video monitoring method is to obtain the icing image of the transmission line through the camera and process it, and extract the boundary contour to estimate the ice thickness on the transmission line. However, there are many difficulties in the actual application of the video method. The quality of the monitoring system used in the video monitoring method The size of the camera is large, the installation angle of the camera is demanding, and it is easy to cause distortion of the monitoring image. Especially when the icing is serious, the camera is covered by ice and snow and it is difficult to capture the icing of the transmission line. As a

Abstract

The invention provides a power transmission line covered ice monitoring device based on a rotation reference conductor. The power transmission line covered ice monitoring device at least comprises the reference conductor, a hanging support and a tension sensor. The reference conductor can be rotationally connected with the tension sensor. The tension sensor is fixedly connected with the hanging support. An ice melting unit is arranged in the reference conductor. The reference conductor rotates under the actions of wind force and covered ice gravity so that uniform cylindrical covered ice can be formed on the surface of the reference conductor; the tension sensor is utilized for monitoring the weight of the covered ice to carry out simulated monitoring on the covered ice of a power transmission line, the covered ice of the power transmission line can be effectively monitored, the effect of the environment on the monitoring result is effectively avoided, and the covered ice monitoring accuracy can be greatly improved.

Description

Technical field [0001] The invention relates to the field of power equipment, and in particular to a transmission line ice coating monitoring device based on a rotating reference conductor. Background technique [0002] In the environment of low temperature and high humidity in winter, high-voltage power transmission lines will experience ice coating. Severe ice coating will lead to the collapse of transmission line towers, wire breakage and other major accidents that affect the safe and reliable operation of the power system, causing large-scale power outages. Seriously affect industrial and agricultural production and people's lives, and cause huge economic losses. [0003] At present, the main methods of icing monitoring on transmission lines are video monitoring and manual line inspection. The video monitoring method uses a camera to obtain the icing image of the transmission line and process it, and extract the boundary contour to estimate the thickness of the icing on the tr...
